I started Fosamax, 8 months, then went on Reclast (after MUCH worry) 4 months after stopping Fosamax. Dexa improved a bit on Fosamax; no more testing until July 2026. First appointment was a script for Fosamax (we didn't really discuss other drugs other than Prolia which the doc does not like), he mentioned Reclast at that first appointment which really scared me as it is a once-a-year infusion so if there is a problem you are stuck. After Fosamax however (some GI issues but not bad) I did as I was told and had the reclast infusion. Doubtful I will do it again unless I can get a half dose; too much worry; seems like some of these drugs are worse than the disease. Reading about people fracturing while ON bone health drugs makes me think twice about the quality and purpose of the meds. That being said I had zero side effects; other than a bad headache on day 5 which cleared up in a couple of hours. Now however I am having bone pain - feet, forearm, leg, thumb joints. Nothing horrible but still an annoyance. Pain in foot bad enough that I am going to the foot doc. So far I have never had a fracture, other than broken wrist from car wreck (EMT said happens all the time, airbag breaks wrists on people of all ages and health levels). I have heard that bone builders should be first; but that's not what my doc prescribed. We will see!
